The EEPROM Method

EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a nonvolatile CMOS chip that stores information in computers and other electronic devices. It can be programmed using individual bytes, which can be accessible using an address. Each byte is either a 1 (or a 0). When a byte has been written to the chip, it is activated. The bits are encoded into instructions when the byte is read.

When writing to an EPROM, both the source and drain are grounded. A high voltage from the control gate is absorbed through the silicon oxide and is able to reach the floating gate. This causes electrons to flow to it and then become trapped. This causes the gate to change its content from a zero to a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be used to keep state between power transitions. This is essential for ICs powered by batteries since a sudden loss of power can cause the chip to reset.

There are a variety of ways to reprogram an EEPROM, but most of them require that the vehicle be in a specific state at the time. For instance, it might be necessary to disconnect the ECU from the battery or to take the EEPROM out and then connect it to an test board.
